VALVE-CONTROLLING MECHANISM.

Application filed January 28, 1907. Serial No. 354,574.

The lurlhcr object ol this invention is to automaticallv start lhc clock movement upon the completion ol' the winding ol the main spring.

in the au-ompanying drawings, Figure l is a lace I representatiou ol' the valve and its controlling mechanism as seen lrom the dial side. Fig. a lace representatitm in which the lace plate is removed. Fig. 3 is a top view. Fig. -I is a perspective view of the starting arm and pointer. l i is a detail view ol the clutch connection with the intermediate wheel. Fig. ll is a detail view ol' the reverse side oi the clock lrame.

. The clock mo rcmcnt is ol the usual construct ion and comprises the mai... spring I, main spring shall 2, escape 7 Pallet l. t'ork halance wheel I"), an intermediate wheel 7 and the train ol gears connecting the main spring I and halance wheel 3.

To the main spring shalt 2 is lixedlv connected a project ion 8 which extends radially therefrom, and to this shaft is fixedly connected an arm 9 lormed ol spring material. The intermediate wheel 7 is loosely mounted on its shall it), and a sliding clutch 'l'l lorms a connee tion between the shalt and intermediate wheel. The section ol pipe i2 is provided with a valve or cock ]3, lo the projecting end of which is fixedly connected an arm l-l ol spring n'talerial. A. pin is inserted in the pipe 12 with which the projections lo and 117 ol the valve engage. The pipe section is a part ol the supplying pipe leading to the burner.

A lace plate 18 is connected to the movement lrame. and is provided with a dial li, divided into hours and lraclions thcrcol. l\ stud 2t) extends l'rom the lace plate.

The main spring shalt 2 projects through a central openiir 2i in the lace plate, and on which is loosely pivoted an arm 22. This arm has an inner section 23 to which is connected a hook 24. A stud 25 connects the bar and inner section and is located in the path ol the movement ol the project ion 8.

A rock shalt 26 is supported by the movement l'rame and is located adjacent to the lork From one end ol this rock shalt extends a projection 27 which is located in the path oi the movement ol the hook 24 and lrom the other end ol the rock shalt; extends a projection 28 to the free end ol which is connected a coiled spring 29. The other end of this coiled spring is connected to the movement lrame. From the rock shalt extends a spring arm 30, its tree end so located that; it will engage the lork 5.

When the parts are in the position shown at Fig. ii. the flow ol gas is shut oil and the projection ll; is a ainst the pin 15. The clock movement at rest owing to the arm 22 resting in contact with the stud and the projection S resting in contact with the stud connected with the bar, and as the projeetimr S is tixedlv connected with the main spring shalt 2 the shalt is held lrom rotation, consequently the main spring cannot act.

In order to open the valve, the arm '22 is moved which will cause the st ml 25 to engage the projection S extending lrom the main spring shall 2 and will 'iaitiallv rotate the shalt, thereby winding the main spring. The arm 22 is moved to move the projection S to the proper hour (let gnated on the dial. This movement of the shalt carries the arm t) to come in contact; with the spring arm l i extending l'rom the valve 13. The valve will he moved into the position shown in Fig. 2 when the projection .17 will strike the pin and arrest its lurther movement.

The arm l) beingol spring material willpass by the arm ll when the parts will appear its shown at Fig. 23.

The arm 22 is then moved so that it will rest, in con tact with the st n d 20, and in returning into this position, the hook 24 will engage the projection 27 ext ending lrom the rock shall 20 thereby oscillating the rock shalt sullicientlv to bring the spring arm 30 against the underside ol the lork and move it, thereby starting the balance wheel in motion. The coiled spring 2.) will hold the spring arm 30 lree ol the lork and permit the hook to pass the projection 27 when the linger is moved to wind the movement.

The spring arm 9 will come in contact with the spring arm l t when the movement is running and move the valve and close it. The arm being of spring material will pass the arm ll extending lroni the valve ill. and when the projection 8 comes in contact with the stud connected to the arm 22, and as the linger is resting in contact with the stud 20 the main spri shalt will be held lroni lnrlher movement, thereby stopping the running ol the movement.

ll it becomes necessary to close the valve het'ore the predetermined time has elapsed, by means ol the rod St the clutch section ll can he disengaged from the intermediate wheel 7, which will permit the train ol' gears between the intermediate wheel 7 and the main spring '1 to run more rapidly, thereby accomplishing the closing movement 01 the valve.

I claim as my invention.

1. A valve controlling mechanism comprising a tim movement: having a main spring; shalt, a spring arm mow able with the shalt, a valve, an arm connected with the valve and located in the path 01"; the movement ol. the spring arm, stops for the movement ol? the valve in both directions, and means for manually turningthe shalt thereby winding the main spring.

2. A valve controlling mechanism comprising a time movement having amain spring shaft, a sprint; arm movable with the shaft, a valve, an arm connected with the valve and located in the path of the movement of the spring arm, stops for the movement of the valve in both directions, a lever pivotally connected with the shaft and a projection extending from the shaft with which the lever contacts.

A valve controlling mechanism comprising a time movement having a main spring shaft, a spring arm Inovable with the shaft, a valve, an arm connected with the valve and located in the path of the movement of the spring" arm, stops for the movement of the valve in both directions, a lever connected with the shaft, and a sta' tionary dial provided with hour divisions over which the lever moves.

4. A valve controlling; mechanism comprising a time movement having a main spring shaft, a spring arm movable with the shaft, :1 vlave, an arm connected with the' valve and located in the path of the movement of the sprin arm, stops for the movement of the valve in both directions, a lever pivotally connected with the shaft, a stop for the lever, a projection extending from the shaft with which the lever contacts, and a stationary dial provided with hour divisions over which the lever moves.

A valve controlling mechanism comprising a time movement, a valve, means operated by the time movement for closing the valve, means for winding the main spring of the time movement, said means also giving a starting impulse to the time movement when returned to its normal position.
